Intended audience: users, XHTML/HTML coders (using editors or scripting), script developers (PHP, JSP, etc.), CSS coders, Web project managers, and anyone who wants to know about encodings in current browsers.
These tests check whether user agents decode characters for a given encoding as specified in the Encoding specification when preferred labels and aliases listed in the spec are used.
Note that the snapshot summaries of these test results are for released versions of the browsers tested. Versions that are still in development may provide better support for these features. The tests themselves do not test any vendor prefixes.
The tables show results for tests run on the date shown. Above the tables are summaries of the results at that date. The table data may be more up-to-date than the summary. If the tables contain some incorrectly scored tests, or tests that relate to non-released versions of browsers, these are not included in the summary.
To see the test, click on the link in the left-most column. To see detailed results for a single test, click on the link in the right-most column.
The top row of each table shows support for the preferred name for the encoding.
The summary only discusses the failures.
Chrome and Opera don't support ibm866 or any of its aliases. (However Chrome support is on its way.)
IE supports it, but not the csibm866 or 866 aliases.

IE doesn't support this encoding using the cp1251 alias.
In rows 9, Firefox doesn't pass through one character that is undefined in the Unicode mapping tables. Instead it returns FFFD. (There is a Mozilla bug to fix this.) All aliases behave the same way.

With the preferred label, IE produces 3 PUA characters where U+FFFD was expected, but doesn't support any alias.
In rows 8 and 9, Firefox doesn't pass through the 14 characters that are undefined in the Unicode mapping tables. Instead it returns FFFD. (There is a Mozilla bug to fix this.) All aliases behave the same way.
Safari, Chrome and Opera pass through one character in row A that has an undefined mapping in the Unicode mapping, where U+FFFD was expected. This appears to be a bug, since undefined mappings in rows D and F produce U+FFFD, as expected.

Uniquely, Chrome, Safari, Opera produce 8 PUA characters equally spread across rows D and F for undefined mappings in the Unicode mapping tables. The Encoding spec expects U+FFFD, and Chrome, Safari and Opera do this for other encodings for characters in in rows A and above. The PUA characters are, in this case, the same as those produced by IE.
IE has no support for this encoding under the 2 aliases shown in red.
In rows 8 and 9, Firefox doesn't pass through the 23 characters that are undefined in the Unicode mapping tables. Instead it returns FFFD. (There is a Mozilla bug to fix this.) All aliases behave the same way.
